mgr/smb: fix error handling for fundamental resource parsing

When an smb resource is input to the smb mgr module in YAML or JSON the
fundamental parsing/deserialization is handled by resourcelib. This
module tries to be largely independent of smb mgr module and defines a
few basic exception types. When these exception types were raised the
`ceph` command line would print out a long traceback. Avoid printing
a traceback by catching these errors with a new contextmanager
(decorator) that is automatically called when using the smb ceph
mgr command api.
